Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To enhance cover ratio of a semiconductor integrated circuit, remove loading effects and enable fine processing by a method wherein a dummy pattern generation prohibition area is provided and dummy patterns are formed in an area excluding the prohibition area. SOLUTION: On a surface of a semiconductor substrate 1, a transistor area 3, a polysilicon wiring area 5 and a metal wiring area 7 are formed. On the semiconductor substrate 1, a dummy pattern generation prohibition area 15 is set, and on an area excluding the dummy pattern generation prohibition area 15 on the semiconductor substrate 1, dummy patterns 11 are formed. Thereby, cover ratio of polysilicon or aluminium can be raised, and a reduction in manufacturing yield of a chip can be suppressed by removing loading effects. Further, as the added dummy patterns 11 are not overlapped on or close to a metal wire and a polysilicon wire, it gets off without increasing incremental wiring capacitance. For this reason, deterioration of circuit operations on circuit characteristics can be suppressed at minimum.
